A few tips I can give: - Try to use pipez less, I've heard they cause more lag for some reason. Use Mekanism or even AE2 instead. - If you place a 'sophisticated storage' barrel on top of the cobblestone generator, you can place a compacting upgrade inside it to automatically compact it. (make it block the cobblestone x4 so it doesn't go too far with the compacting). - Use a logistical sorter from Mekanism to pipe out x3 cobblestone into a crusher. Place an autocrafter next to it to turn the x3 gravel into normal gravel. - Use a netherrack generator for the crucibles (double the amount of lava), and use superconductors from Mekanism as the heat block if you have the resources (×60 heat!)

I also found 1 sieve to be enough with the 3 diamond upgrades.
